12. Use Case Lessons Learned • Identify “collective results” of looking at several use case • Communications system management • Sensor management • Work flow management • Implications for next steps • The majority of the cases related to workflow management – this area appears to be offer more opportunity for development • Suggestions on how to promote use cases • Use the “value chain” analysis (more science? Better science? Cheaper science?) • Emphasis on simplification through abstraction… • Use animation / DVD • Live demonstration • Provide feedback to ESTO AIST team • The use case work should not wait another year – this should be an ongoing area of interest Sensor Web Meeting, Working Group Middleware II

13. New Sensor Web Features, Needs • Identify new features or benefits • Inclusion of a broader discussion of interoperability • List any new AIST needs Sensor Web Meeting, Working Group Middleware II

14. Recommendations • Suggestions for ESTO next steps • Continue to refine use cases • Closer look at decadal survey relevance • Perform value chain analysis • Perform mashups of cross cutting use cases • Crosscutting PI teams • Identify specific individuals for sensor web follow up • How can AIST or info systems in general, influence planning for Decadal Survey missions • Bring John Garstka to the “big” meeting with the HQ mission managers Sensor Web Meeting, Working Group Middleware II
